Uncooled High Speed Ge/Si Avalanche Photodiode for 50 Gbit/s-PON with 60 km Reach
Résumé
A high-speed germanium on silicon APD is demonstrated for DSP-free 50G-PONs. Sensitivities of -24 dBm at 58.2 Gbit/s and -26.5 dBm at 50 Gbit/s over 60 km of fiber are experimentally obtained in real time with temperature from -40 degrees C to 80 degrees C. (c) 2022 The Author(s)
